Potential of garlic oil as a biopesticide against all Aedes aegypti life stages

Vector control remains the most effective approach to prevent dengue, chikungunya and Zika arboviruses transmission. Conventional insecticides have historically failed Aedes aegypti mosquito due acquired resistance, environmental impact toxicity. This study evaluated potential of garlic oil as a biopesticide against eggs, larvae, pupae adult forms Ae. aegypti, in accordance with World Health Organization recommendations. The larvicidal pupicidal LC50 values were 1.0 ppm 20.3 after 72 h, respectively. maintained its activity simulated field trials, killing all larvae at concentrations tested. At 100 ppm, inhibited 59.6 ± 10.6% egg hatching. Toxicity form was observed potent spatial repellency. Garlic oils composed different diallyl polysulfide ratios did not significantly insecticidal although mixtures more than isolated polysulfides. ovicidal, larvicidal, pupicidal, adulticidal repellent assays showed broad aegypti. These results, together support applicability an integrated vector program.
